COMBINED SLIDING AND SWINGING SASH.

SPECIFICATION forming part of Letters Patent No; 615,777, dated December 3, 898. Application filed April 14, 1898. Serial No- 677,612. (No model.)

T at whom it may concern:

Be it known that I, ROBERT ADAMS, engineer, a subject of Her Majesty the Queen of Great Britain,residing at 67 Newington Cause way, London, S. E., England, have invented certain new and useful Improvements in a Combined Sliding and Swinging Window- Sash, of which the following is a specification.

The objects of my invention are to construct Window=sashes in such a manner that they may be capable of sliding vertically in the usual manner and also that the outsides of the sashes may be turned into the room upon horizontal pivots; to effect the conversion of ordinary windowsashes into revolving, reversing, or swinging sashes; to effect improvements in the fittings applied to such sashes, and to simplify such means and operations, so as to facilitate and reduce the cost of effecting the same.

In order that my said invention may be particularly described and ascertained, reference is hereby made to the accompanying drawings, in which similar figures of reference indicate corresponding parts.

Figure 1 is a general perspective view illustrating the application of my invention to sliding window-sashes fitted with pivots to enable them to revolve upon horizontal centers, hereinafter referred to as swing window-sashes. Fig. 2 is a horizontal section showing one method of fitting my improved pivots to swing window-sashes. Fig. 3 is a vertical section showing my improved method of fitting the tongue for excluding draft between the stile and slip. Fig. 4 is a detail side view of the same. Fig. 5isadetail View of one of the cams used in operating the tongue. Fig. 6 is a front view of another form of' cam for actuating and securing the tongue, and Fig. 7 is an edge View of the Fig. 8 is a sectional elevation of a swing window-sash, showing the stile and slip drawn together by screws and the tongue propelled into the groove in theslip to exclude draft. Fig. 9 is a section on the line ab of Fig. 8. Fig. 10 is a detail drawing showing the screw and tongue vwithdrawn. Fig. 11 shows another method of fitting the tongue. Fig. 12 is a side View of the same.

Fig. 13 is a section showing another means of like.

Referring to Fig. 1, 41 is the upper swing window-sash, fitted, as described, for cleaning and other purposes, and 40 is the lower swing window-sash.

Fig. 2 illustrates one of my improved methods of fitting pivots to swing-sashes. 42 is the stile, and 43 the slip. The stile is fitted with a metallic brush 44, in which the neck of the screw-pivot 45 is held, as shown. The screwed portion of the pivot meshes with a metallic lug 46, attached to the tongue 47, whereby the tongue can be projected into the groove in the slip or withdrawn therefrom by a half-turn or otherwise of the screw. The plain end of the pivot passes through metallic bushes 48 49, fitted to the stile and slip, respectively. When the tongues are withdrawn from the slips, as shown in Fig. 2, the sash is capable of being swung upon its centers, as shown in Fig. 1.

Figs. 3 to 7 show other methods of mounting and operating the tongues. In Fig. 3 the pivot 45 is shown by dotted lines, with ascrewthread at the end meshing with a screwed socket 60, fitted to the slip 43, the plain part of the pivot 45 passing through the bush 61 and stile 42. In the same figure, coupled with Fig. 5, is shown a method of fitting parallel-motion tongues to both swinging and hinged sashes. I 52 is a lever pivoted at 58, the upper end of the lever being fitted with a projecting cam 54. This end of the lever passes into a recess 55, formed in the slip 43, where it clips the back of a plate 56, attached to the same slip 43, as shown in Figs. 6 and 7, whereby the stile and slip are drawn together and locked. The lever 52 may be turned in either direction by means of a nail or other suitable article inserted in the gap 57 or by a square-ended key inserted in the hole 58 or by other suitable means. allelism of the tongue 47 is secured by means of two or more levers 52, as indicated in Figs. 3 and 5. The tongue 47 is secured to each lever 52 by pins 59.

Figs. 8 and 9 show another form of pivot 45, the end of which is hard screwed into a plate 60, secured to the slip 43. The stile 42 is hushed at 61, and the sash revolves upon the plain end of the fixed pivot 45. 62 62 are preventing draft in sWing-casements and the The parthreaded screws, having an annular groove forming a neck 63. The screw meshes with the threaded socket 64. Brackets 65 (forked or otherwise) are fixed to the tongue 47, the forks embracing the neck 63 of the screw. On turning the screw forward the stile and slip are drawn tightly together, and the tongue 47 is projected into the groove in the slip simultaneously, thus forming a weather-tight joint, as shown in Figs. 8 and 9, and on withdrawing the screw 62 the stile is detached from the slip and the tongue is withdrawn from the groove in the slip, as shown in Fig. 11. The sash is then free to swing upon its pivots.

Figs. 11 and 12 show another method of fitting swinging windowsashes.

In Fig. 13 is shown a construction for excluding drafts in swing-windows. It consists of a tongue 8:2, which is held in place in a groove in the casement, a channel being provided in it to receive a head or offset 82 on the frame.

I claim-- 1. In a combined sliding and swinging window-sash, the combination with the slip and stile of a thumb-screw having a threaded end engaging a threaded socket in the slip, a lug or bracket having a fork which engages a plain portion of the thumb screw, and a tongue adjusted by said lug, or bracket, and lying in a recess formed partly in the stile and partly in the slit, substantially as described.

2. In a combined sliding and swinging window-sash, the combination with the stile and slip, having metallic bushings set in their adjacent faces, of a pivot-pin having a threaded end engaging athreaded socket in the bushing in the slip, and a plain portion lying in an opening in the bushing in the stile, substantially as described.

3. In a combined sliding and swinging window-sash, the combination with a slip and stile of a tongue lying in a recess formed in their adjacent faces, a pivot-pin having plain end engaging openings in metallic bushings set in the adjacent faces, and a ing forming a rigid part of the tongue and having a threaded socket for a threaded portion of the pivotpin, substantially as described.

4:. In combined swinging and sliding sashes the combination with the lever 52 of the cam 54-, adapted to engage the plate 56 attached to the slip 43, whereby the stile and slip are drawn together and locked, substantially as described.

5. In combined swinging and sliding sashes the improved device for locking the stile and slip together and operating the tongue, consisting of a screw having a milled headintegral with a stem 62, a reduced neck 63 and a threaded end meshing with a screw-threaded socket 64, and forked brackets (35 fixed to the tongue embracing the neck 63 of the pivot, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IlGSSQS.
